Background

Forta

Forta is a real-time detection network for security monitoring of blockchain activity.

Forta comprises a decentralized network of independent node operators that scan all transactions and block-by-block state changes for outlier transactions and threats. Developers can build Detection Bots (piece of script that monitors the activity) and machine learning models, which are run on the network.

Multiple Phishing Attacks Drain Millions on Ethereum Despite Early Detection

Thu 31st Jul 2025
A series of costly phishing attacks hit Ethereum Mainnet in July-August 2025: - $300K lost despite Forta Firewall's early warning (4-hour gap between detection and victim approval) - $3.1M phishing attack occurred with 1.5-hour warning window - $730K stolen from SuperRare due to access control vulnerability - 1,069 malicious contracts identified, stealing 181.5 ETH + tokens worth $868K Forta Firewall detected all threats at contract deployment, but victims proceeded with transactions on unprotected chains. These incidents highlight the critical need for active security measures beyond just threat detection. *Key takeaway*: Early warning systems require protective action to prevent losses.

DeFi Attacks from Private Mempools Surge to 48%

Tue 15th Oct 2024
DeFi attacks originating from private mempools have increased from 14% to 48% in just two years. These hidden pools bypass traditional defenses, posing a significant threat to crypto security. Private mempools allow attackers to execute transactions secretly, evading front-running defenses like protocol pauses or rescue transactions. Forta Firewall offers a solution by: - Simulating transactions in real-time - Blocking malicious actions from private mempools - Preventing attacks without pausing protocols or affecting legitimate users As DeFi attacks evolve, prevention becomes crucial. Learn more about mempool risks and Forta Firewall's protective measures in the full article.
